A small video of a 400Amps fuse was taken which was about to fail. The base unit completely cracked due to heat produced by the sparking fuse contacts. Finally causing the relays to fail in power panel.
A call was logged in EB for replacing the fuse with carrier and base unit.
I got an LED lamp with remote control from Santhosh Electronics. This is going to be very useful to me as i may switch on and off the bulb as per my convenience from a distance. The remote operates under infrared led and is powerful in transmission. I tested the coverage distance of the infrared and found working at 10 meters. The lighting is good enough with the 30 nos Cool daylight white led. This product is branded OXYGEN from chennai and this one carries warranty for 15 months. Very rarely such LED products come with warranty. I am planing to mount one in office server room. A similar china product is available which has a physical switch. It requires us to switch manually. Practically this bulb is mounted at the top and there is no meaning in keeping a manual switch. Previously every time when power fails during the day time, the bulb is lit and i had to climb and switch off manually.
The backup time is expected for 3hrs. The bulb has an red led for charge indication. The White color plastic base and the white light adds attraction to the room. The life of a LED is higher when compared to other lamp. so LED lighting is cheaper comparitively.
Operation: The bulb has a manual switch to totally turn off the device receiver. When we turn on this physical switch, it turns on the receiver and enables us to switch on the light. The remote has single button switch used to switch on and off the IR transmitter. When the bulb is in charge and the AC power goes off, it stays off in the previous state. When the bulb is in charging and ON, it uses the AC power to glow. When AC power goes off, it continues to glow automatically switching to DC. Either way the bulb maintains its state.
TECHNICAL INFO:
No of LED’s = 30 Nos
Input Voltage = 220V, AC
Backup time = 3Hrs
Remote Operation = Infrared
LED TYPE = Cool day light LED
Warranty = 15Months, Inclulding LED.
Remote Battery = 2 X AAA Cell
Bulb Battery = Sealed Rechargable Cell
The bulb comes for Rs.375/- and not going to cost you much to try one.
1000 WATTS STANDARD STABILIZER is the solution.
I have recently taken a stabilizer at SHAH Electronics in ritchie street, Narasingapuram.
This stabilizer is an ideal one to run a common computer. This Stabilizer is an Triple boost and boosts voltages from 125V into 240V. This is a fully automatic stabilizer. There is absence of manual control switch which is not required here. I watched the sales person test the Stabilizer with auto transformer and could not believe i am going to take one. I am living in puzhuthivakkam where the voltages drop to 140V not allowing to power my PC during night. I was searching for an solution and my friend insisted me to take this stabilizer. Now i am happy that i can run the PC at nights too.
The 1000 watts stabilizers delivers power nearly 1.5Kva, which is enough to run two powerful PC without any fear. This practically works from 130V and never lets the UPS or Inverter to drain. One of my friend has taken this after seeing its performance and he’s happy that he saved the costly inverter battery getting damaged from frequent voltage fluctuations. This stabilizer may suit other appliance also but be sure to check the wattage does not exceed 800 watts.
Capacity : 1000 Watts
Input Voltage : 125V~255V
Output Voltage : 200V~240V
Voltage Control : Fully Automatic
Input Volt meter : yes
Output Volt meter : yes
Input Power cord : 5A
Output Socket : 5A
Fuse : Wired Fuse

USE ENERGY, BUT DON’T WASTE ENERGY
Recently, a lot of ads show us that we should GO GREEN. But most of them do not guide us how to do. Here are a few tips to do to keep the planet green.
Plant More Trees
Grow more trees as much as we can. The trees take care of the CO2 level and keep this earth cool and maintains green. Falling more trees from this planet is nothing but killing our own kind. Our only hope is trees. Read the rest of this entry »
Even today most of technicians have the doubt of what all are differences between xp and 2000. here are a list of differences for you.
Although XP is superior and faster than 2000, most people want to know more of the comparison. Hope you got your answers today.
The problem that happens when we connect two or more, different brand of RAM or different size of RAM or different frequencies in a same PC is called FREQUENCY MISMATCH. This effect is not found most of the time immediately when we connect and power on the PC. This does not give any RAM beep to warn you. When there is a mismatch we cannot boot the OS properly, cannot copy files from one location to another, cannot compress or decompress files, and cannot run application that requires RAM resources. Of course this will show increase in size after connecting, but know that you are going to damage your RAM.
The cause for this problem is the RAM cannot withstand the operating frequency of each other as each RAM will produce an error while working. This varies with manufacturer and when this exceeds the limit, the RAM chip gets damaged. This slowly develops and at a stage creates trouble.
I myself practically tested this effect with two different size of RAM (128MB+64MB) showing 192MB, I could use the PC for about three months without any problems but later the OS crashed. I tried loading new OS, but it failed to install. Then I found that one of my RAM (64MB) developed unrecoverable damage in it.
Even after knowing this problem I made a mistake. In my office I connected four RAM of same frequencies, same size but different brands. For one week only the PCs were stable and I got the same annoying symptoms. Then when I tested I could find a RAM damaged internally and giving problem in performance. Please protect your PC without damaging hardware. So guys do not try this at home and cause damage to your loving PCs.
Having a single RAM module is OK but you might lose certain performance like dual channel mode. When buying two or more RAM for a single PC, see that you get the similar RAM delivered in the SAME BATCH. This will avoid any problems regarding the Frequency Mismatch.
The power saving has become an essential requirement all over the world. We need to have advanced and more efficient configurations to be made to make more performance with less power loss. Most of the time we keep the PC powered on without any task. This consumes a lot of power. Power cuts are frequent due to the shortage in generation of Electricity. We can’t burn lot of fuel in generators as we all need a Green planet.
Microsoft has found solution for making the planet greener and made improvements in the configurations of power in Vista. These options are much better than XP and previous versions of its operating systems. We much advanced options that practically suit every user environment.
To change your power settings go to Control options, power options, choose any preconfigured plan or make your own configurations from the options available.
We can configure, start menu power button options, turnoff hard disks when idle, change wireless adapter setting, sleep settings, USB power, PCI Express Link state power management, processor power management, Search and indexing, Display power setting, windows dream scene setting, multimedia setting.
Use these options to save power and consume less carbon emitting fuels those cause the Global Warming. Please help to keep the planet green. We need this green planet for our future generations.
When we buy a PC we see the capacity of RAM by its size, there is another factor to consider, it’s Frequency or Working speed of RAM. RAM frequency has been updated most of the time and we are not able to judge what we need to buy. Here is a list of RAM upgrades and specifications. Plan before you buy one of them.

To check this feature, go to Control panel, open performance information and tools, click update my score.
The windows experience index is a new feature available in windows vista. If you have installed vista newly then you got to check the performance of the hardware components. Ratings are available for hardware, especially Processor, Memory, Graphics, Gaming Graphics and Primary Harddisk. Sub score are displayed for these components and base score is taken out of the sub score.
The base score is the least score achieved by the hardware. The lower base score means the lesser performance from the hardware and more the base score, the better performance you’ll have. Based on this analysis you can plan to buy your software that works best for your system. The score ratings ranges are 1.0 to 5.9, where 5.9 is the top score you can target.
Every time you install windows vista (or) new hardware, you need to update the score for vista to recognize the added performance. Windows aero will start after you install the drivers for graphics card and your base score updated. Aero requires base score 2.0 or above to work. If you have base score 1.0 you can run office application and browse internet, but you cannot use vista’s graphics demanding features.
A base score of 4.0 or 5.0 is required to run HDTV content, 3D gaming, Powerful graphics requirement of applications and the most of vista’s full featured animated graphics. The detailed information of the system like total Harddisk, active network adapters, and graphics can also be viewed from the view and print details option.
So if your base score is below 2.0, it indicates that you can have minimal pleasure out of your system, so plan to buy new hardware to improve system performance than blaming Windows Vista.
